UIGestureRecognizer blocks subview for handling touch events

Question

I\'m trying to figure out how this is done the right way. I\'ve tried to depict the situation:

Answer 1

implement a delegate for all the recognizers of the parentView and put the gestureRecognizer method in the delegate that is responsible for simultaneous triggering of recognizers:

func gestureRecognizer(UIGestureRecognizer,       shouldBeRequiredToFailByGestureRecognizer:UIGestureRecognizer) -> Bool {
if (otherGestureRecognizer.view.isDescendantOfView(gestureRecognizer.view)) {
    return true
    } else {
    return false
}

}

U can use the fail methods if u want to make the children be triggered but not the parent recognizers:
